Application filed October 20, 1925.` Serial No. 63,731.

The primary object of my invention is to provide a spring hinge forrefrigerators, of such construction as will permit of its beingmanufactured at extremely low cost and at the same time being a veryefficient hinge;

with this and other objects in View, my invention consists of the partsand combination of parts as will be hereinafter more fully set forth.

In the drawings:

Figure 1 is a front elevation of portions of a door, and a refrigeratorbody, with my improved hinge in position.

Figure 2 is a front elevation of my improved hinge, parts being insection.`

Figure 3 is a sectional view on the line 3-3, Figure 2.

Figure 4f is a front elevation of the two hinge leaves detached.

Reference numeral (1) designates a re frigerator body and the door ofthe same, of suitable construction.

My improved hinge comprises two leaves, (3) and (il). The leaf (4) isprovided at its top and bottom with pintle4 receiving members (5) and(6) and with suitable openings to receive the screws. The leaf (3) isprovided with pintle receiving members (8) and (9) which are spacedapart,

so leaving a space (10) between them which will be hereinafter referredto, this leaf (3) being provided with suitable openings for the screws(11). A suitable housing (12) is mounted on the leaf (3) and secured i5thereto by means of screws (13) but it will be understood that thishousing will be cast integrally with the hinge leaf (3). The housing isopened at one end and has a perforation at the other end through whichthe .0 end of a plunger (14) may slide, said plunger being mounted inthe housing. A coil spring (15) is secured around the plunger (14E)within the housing, one end of the spring being seated on the end wallof .5 the housing, while the other end of the spring is seated on thehead (16) of the plunger. This head (16) has a forked end (17) in whichis loosely journaled a roller (18). A head (16), when the leaves are 0assembled, projects through and moves in the space (10) between thepintle receiving members (8) and (9) of the hinge leaf (3). It will beunderstood that there is a pintle pin (19) mounted in the pintlereceiving members (5) and (8) and also a pintle pin mounted in thepintle members (6) and (9) and that these pintle pins do not extendacross the space (10), thereby leaving the space (10) in the hinge jointfree for the reciprocation of the head (16) in said space.

The leaf (el) is provided with a cam member (20), having the cam surface(21) of suitable contour on which cam surface the roller (18) of thehead and plunger is adaptJ ed to ride.

As the door (2) is opened, the roller (18) moves downwardly on the camsurface (21) toward the juncture of the door and refrigerator body,thereby pushing the plunger (14) rearwardly in the housing and placingthe spring (15) under compression, the construction being such that thedoor is free to be opened to its fullest extent. As soon as the door isreleased, the spring (15) exerts its influence to close the door, theroller (.18) riding up on the cam surface (21) to the position shown inFigure 3 and holding the door tightly in its closed position.

I am aware that changes may be made in4 the details of constructionwithin the spirit of my invention and the scope of the appended claim.

That I claim is:

A door hinge comprising two leaves, the first having pintle receivingmembers at the top and bottom edges thereof. the second of said leaveshaving pintle receiving members kspaced from each other and adapted toabutV the pintle members of the other hinge leaf, a housing on thesecond of said leaves, a cam on one, the first mentioned leaf projectingfrom the first of said leaves between` the pintle receiving members ofthe second of said leaves, a spring impelled bar mounted in said housingand projecting transversely of the hinge joint between the pintlemembers of second named leaf and engaging the cam on the first namedleaf.

In testimony whereof I aiiix my signature.

ALFRED E. TI'IUS.
